硬实种子不透水，必须经过适当处理来提高种皮的透性种子才能萌发。

Hard seeds whose coats must be properly treated so that permeability is increased without injuring the embryo .

硬实种子是由于种皮（有时也包括果皮）坚硬而很难进行吸胀萌发的种子。

Hard seeds which theseed coat ( sometimes including the peel ) are hard and difficult to imbibe and germinate .

建议在测定豆科牧草种子的活力时，可以考虑将单独测定硬实种子活力作为种子质量评价指标的补充。

The vigor of hard seeds could be tested solely as the complementarity in the evaluation of legume seeds quality .
